The two-Test tour to Argentina in June will be headed by Frank Hadden, who will be assisted by Sean Lineen and Andy Robinson – invited to join the Scotland team after a disappointing 2008 RBS 6 Nations.

Lineen's appointment could have heralded the departure of Tait given both are specialist backs coaches, but former Lions star Tait has been retained at least until after the summer tour in order to work on the team's defence - his particular area of expertise.

The management team will also include Duncan Hodge (place and line kicking) and Mark Bitcon (strength and conditioning).

SRU chief executive Gordon McKie said: "There is a wealth of experience of both the international game at the highest level and a detailed knowledge of Scottish professional players."

Meanwhile, the Scotland A squad that will compete in the Barclay’s Churchill Cup in North America will be under the direction of Rob Moffat, who has been a professional coach in Scotland for more than 10 years.

Moffat, the backs coach at Edinburgh Rugby, will be joined by Glasgow Warriors forwards coach and former Scotland lock Shade Munro, Glasgow Warriors defence coach Gary Mercer and Scotland 7s coach Stephen Gemmell for their three matches in June.

McKie added: "We have now completed our review of the RBS 6 Nations and the coaching teams we have put in place for the Scotland and Scotland A teams will give us the best chance of success next month.

"We are also making alterations to the strength, fitness and conditioning, performance development and other supporting disciplines at Scottish Rugby aimed at further improving preparation of the national squad."
